So I finally got the chance to try the Holy Hydration! Sleeping Mask in White by e.l.f. Cosmetics, and I must say, I love e.l.f. products. This mask can be used all night or as a 10- to 15-minute mask. As soon as it was applied, it felt like a refreshing glass of water for the skin. The high-duration hydration was amazing. Janell decided to wear it all night and will provide an update later. If you're looking for a hydrating mask, give this one a try.
